ACPICA commit 129b75516fc49fe1fd6b8c5798f86c13854630b3
Stop nagging user about every Stall() that violates the spec
On my Dell XPS 15 7590 I get hundreds of these warnings after few hours of uptime:
$ dmesg | grep "fix the firmware" | wc -l 261
I cannot fix the firmware and I doubt that Dell cares about 4 year old laptop either
